I purchased two of these for my family to go out on the bike trails. I am very happy with them. Good quality and lots of power. Can go up hills with no hesitation. Great features like brake lights, headlights, cable lock, phone holder. I am happy with the mileage we can get on these. Can easily do a 15 mile trip and battery will still be around half full. Can easily hit between 27 and 30 mph depending on how full battery is. I am 6 foot 3 inches tall and 210 LBS and the bike still fits me, wife is 5ft, 10 and she enjoys the e-bikes also. I am spending great quality time with my family this summer in our biking adventures!!
